Summary
Stimuli-responsive polymers show increased protein adsorption when collapsed versus swollen. This controllable protein interaction is key for biomedical applications, though reversibility and time-dependence require further study.
Area of Science:
- Polymer Science
- Biomaterials Science
- Surface Chemistry
Background:
- Stimuli-responsive polymers undergo reversible volume phase transitions.
- Protein adsorption on biomaterials is crucial for biomedical applications.
- Few studies link protein interactions with stimuli-responsive polymer transitions.
Purpose of the Study:
- To review protein adsorption dependence on polymer volume phase transitions.
- To highlight thermoresponsive polymers as a key subset.
- To identify knowledge gaps in protein-biomaterial interactions with these polymers.
Main Methods:
- Literature review focusing on protein adsorption and stimuli-responsive polymers.
- Analysis of existing studies on protein-biomaterial interactions.
- Generalization of findings to materials with reversible volume phase transitions.
Main Results:
- Increased protein adsorption observed in the collapsed polymer state compared to the swollen state.
- Findings are generalizable across different stimuli-responsive polymer systems.
- A clear trend of higher protein adsorption in collapsed states is reported.
Conclusions:
- Stimuli-responsive polymers offer tunable protein interaction control for biomedical uses.
- Further research is needed on the reversibility and time-dependence of protein adsorption.
- Understanding these interactions will advance theoretical models and applications.

15.0K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

01:30Modified-Release Drug Delivery Systems: Stimuli-Activated
112
Stimuli-activated drug delivery systems are designed to release drugs in response to specific physical, chemical, or biological stimuli. These systems often utilize hydrogels—three-dimensional, hydrophilic polymer networks capable of swelling in aqueous environments and retaining significant fluid volumes. Upon exposure to particular stimuli, these hydrogels undergo structural transitions that allow the embedded drug to be released. Due to this adaptive behavior, such systems are also...

Polymeric carriers enhance targeted drug delivery by increasing efficacy while minimizing off-target effects. These carriers comprise a biodegradable polymeric backbone integrated with functional elements that enable targeting, improve physicochemical properties, and regulate drug release.Targeting MechanismsThe targeting ability of polymeric carriers is mediated by a homing device, which is a molecular recognition component designed to selectively bind to specific tissues or cells. Monoclonal...
